北方农村婴幼儿简易辅助食品的实验研究

A Simple Supplement Food for Infants in Northern Countryside of China

研制一种原料来源广泛,价格低廉,营养合理,配制简便的婴幼儿辅助食品(简称配方食品)。配方食品以小米粉、白面粉为主,混合适量黄豆粉、鸡蛋、并强化碳酸钙、核黄素等。同时进行营养评价。结果:配方组动物的体重增长,血红蛋白、血清蛋白含量和骰、胫骨长度都与酪蛋白组无明显差异(P＞O．05);校正 PER为 2.24,达酪蛋白值的 89．6%;NPR为 3．99、PRE为 65．67%,分别达酪蛋白值的 91%以上;TD为86．2%;BV两组无明显差异(P＞O．05)。两组都达正氮平衡。

This formula consisted of millet meal , wheat flour , mixed with appropriate amount of egg, soybean flour , and fortified with calcium carbonate and riboflavin. Animal experiment: 30 weaning wistar rats were randomly divided into 3 groups: (A) casein group. (B) formula group, (C) No nitrogen group. The results showed that body weight gain, Hb, serum protein content, Lengths of cuboid and shinbone were not significantly different between of group A and B (P>0. 05) .The calibrated PER, TD, BV and NPU group A were 2. 5, 92. 5%, 74. 1%, 68. 5% and of group B were 2. 24, 86. 2% , 69. 1 % and 61.3% respectively. Both groups obtained the results of positive nitrogen balance, no significant statistical difference. was found. These data demonstrate that this formula is able to promote the growth of weanling rats and retain positive body nitrogen.
